[QUOTE="Evans Electric, post: 498626, member: 1408"] Could be a 32 A / 30mA RCBO , possibly sandwiched between two other devices ,,, the thermal part of the overload overheats during showering , finally trips even after shower is finished. The unit must operate on around 35A . I've known showers work on the old 30A breakers with a downstream RCD, they work because a shower is usually over in say 10 mins . I have a customer who takes foster children for short periods ......one of them used to run the shower for more than an hour ( no idea why) which melted those two 16A micro switches that switch the two elements in .
